South Africa July this year - should I take anti-malarials?

The little bastards are less active now until August/September, but for peace of mind you could take precaution. However...I would rather just recommend mosquito repellant and a mosquito net rather than the tabs, since they are known to only mask the effects of malaria and not prevent it. Many cases have been reported where people used the tabs, got sick, were diagnosed with flu and eventually passed because of malaria.
